I came upon this question :
and based on the answer and the comments on the answer :
the kernel memory map includes a direct mapping of all physical memory, so everything in memory appears there; it also includes separate mappings for the kernel, modules etc., so the physical addresses containing the kernel appear in at least two different mappings
Is this true? I couldn't find any source or reference for this, and why would it include a map of the entire physical memory and then again have a separate mapping of kernel modules? Isn't that redundant?
Can someone explain in a simple manner what is inside the kernel part of virtual memory of processes in 64-bit Linux? and please provide a source for the answer! because I couldn't find anything related to this in any book or paper.
